This patch introduces another two options to get/set time with "ktime_t" type in ptp clock operation.
Original code will set/get time through the settime/gettime interfaces with "timespec" type, that will cause break issue in year 2038. And now introducing the new setktime/getktime interfaces with "ktime_t" type to use firstly.
